A hierarchical design of complex interactive interface with multi-perception channels for a helmet-mounted display system of vehicle

Abstract

To expedite the modernisation of equipment construction and address practical challenges, such as low efficiency in armoured vehicle passenger information retrieval, diverse perception channels, and inadequate combat effectiveness in traditional vehicle-integrated electronic information systems, the authors aim to transition to a helmet-mounted display system (HMD). On the basis of the target mission stage of military vehicles, the authors have organised the required information items for the vehicle HMD, integrated the hierarchical relationships of interaction interface design elements, and formulated design strategies using the Garrett user experience element model. We have constructed a vehicle HMD interaction interface design model and conducted comparative experiments with typical vehicle electronic display system interfaces. The usability of the model has been verified through eye-tracking experiments and reaction time analysis. Experimental data indicates that the vehicle HMD interactive interface system, guided by the user experience element model, effectively enhances operational performance for passengers, demonstrating superior recognition, search ability, comprehensibility, and rationality. In conclusion, the vehicle HMD interaction interface design model, guided by the user experience element model, meets the requirements of vehicle HMD interaction interface design. It validates the effectiveness and feasibility of transitioning from a traditional vehicle-integrated electronic information system to a vehicle HMD, providing technical support for enhancing display efficiency in future prototype platforms on the prototype platform digital warfare.
